JAMEs THOMAS JORDAN, or Burns, TEXAS.

COTTON-BLOCKER.

SPECIFICATION forming part of Letters Patent No. 370,875, dated October 4, 1887.

Application filed March 1, 1887. Serial No. 229,327. (No model.) i

To all whom it may concern.-

Be it known that I, J AMEs THOMAS JORDAN, a citizen of the United States, residing at Rupee, in the county of Falls and State of Texas, have invented certain new and useful Improvements in Cotton-Blockers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

and combinations of parts, hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a portion of a cultivator, illustrating the application of my invention thereto. Fig. 2 is a plan view, and Fig. 3 is a detail view of a modification.

Corresponding parts in all the figures are denoted by the same letters of reference.

Referring to the drawings, A represents the axle of a cultivator, B the spindles of the axles, and G the carrying-wheels. One of the carryingwheels is provided with a sprocketwheel, D, as shown. The axle A of the cultivator is provided near one end with a mortise, a, to receive a tongue or tenon, b, which projects downwardly from a gear-supporting frame, E. This frame E is provided with a vertical slot, 0, and horizontal recess (1.

F represents a shaft, which extends through the vertical slot 0, and on said shaft, within the vertical slot, is mounted a bevel gearwheel, G. The end of this shaft extends a considerable distance beyond the gear-supporting frame, and has mounted near its outer end a sprocket-wheel, H, of less diameter than the wheel D, and connecting said wheels D and H is a sprocket-chain, I, so that upon forward movement of the cultivator motion is imparted to the bevel gear-wheel G.

J represents a bevel-gear, which is mounted on the upper end of a shaft, K, having hearing in the gear-supporting frame, said gear J meshing with the gear G, as shown. The up per end of the shaft K is extended beyond the gear wheel, and upon said upper end is mounted a slotted arm, L, in which is adjustably secured a pin, M. The upper ends of the gear-supporting frame are provided with slots f, in which is loosely fitted a rod or bar, N, which has a slotted arm, 0, extending from each side thereof and in line with each other, the slots of said arms also being in line and adapted to receive the pin M, which projects from the arm L. By making the pin adjustable in the slotted arm it will be seen that the length of the stroke or movement of the bar or rod N may be regulated.

On the inner end of the bar or rod N is adjustably secured a collar, 9, through which passes the end of a rod, I, carrying at its lower end a hoe, h.

1? represents the cultivator bars or beams, and said beams are connected by a curved strip, 2', on which is mounted pivotally midway the ends thereof a spool, Q, which has a slot, through which passes the rod P, and which is held firmly and securely in said slot at any desired adjustment by' means of a setscrew, 9', as shown.

The operation of the device as thus described is as follows: Upon the cultivator being moved forward the carrying-wheels revolve and the gear-wheel D is rotated, thus imparting motion to the shaft F through the gear H and the sprocket-chain connecting said gear-wheels. The gear G, meshing with the gear J, rotates the latter and causes the pin secured to the slotted arm to traverse the slot in the arms of the rod N, thus causing said bar to be reciprocated, and, through its connection with the rod carrying the hoe, to operate the latter. By moving the pin in the slotted arm to which it is secured the length of the stroke of the rod N may be regulated.

The device above described is simple in its construction, cheap to manufacture, strong and durable, and effective in its operation.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, -is- 1. The combination, with the beams of the cultivator, of a transverse connecting strip or bar carrying a rod having the hoe at its lower end, a horizontal reciprocating bar connected to the upper portion of said rod and provided with the slotted arms, and gear mechanism embodying a gear-wheel having a projecting pin engaging said slotted arms, substantially as and for the purpose set forth.

2. The combination, with the frame of a cultivator embodying the cultivator-beams and the axle carrying a gear-supporting frame, E, of a transverse strip or bar connecting said beams, a rod carrying the hoe at its lower end and pivotally connected with the transverse bar, a horizontal reciprocating bar mounted in the frame E, and provided with the centrally-located slotted arms and connected at one end with the upper port-ion of said rod, a horizontal bevel-gear mounted upon a vertical shaft and carrying a projecting pin engaging the slotted arms, a vertical bevel-gear mounted upon a horizontal shaft, F, the hevel-gears being mounted within the frame E, and operating mechanism connected with the shaft F, substantially as and for the purpose set forth.

3. The combination of theaXle carrying a gear supporting frame, E, the cultivatorbeams, a transverse strip or bar, a spool pivotally mounted thereon, a rod carried by said spool and having the hoe at its lower end, a horizontal reciprocating bar having the centrally-located slotted arms and provided with a collar at one end, the bevel-gear mounted in the frame E and carrying a projecting pin engaging the slotted arms, and mechanism for operating the gears, substantially as and for the purpose set forth.

4. The combination, with the cultivatorbeams, of a connecting strip or bar, a spool pivotal] y connected therewith, a rod mounted in the spool and carrying a hoe, h, at its lower end, a horizontal reciprocating bar carrying a collar at one end, through which passes the rod, and mechanism for reciprocating said bar, substantially as and for the purpose set forth.

5. The combination, with apivotally-niounted rod carrying a hoe at its lower end, of a horizontal reciprocating bar connected at one end with the upper portion of said rod and provided with the centrally-located slotted arms projecting in opposite directions, bevelgear carrying a pin engagingsaid slotted arms, and a frame carrying the bevel-gear and reciprocating bar, substantially as and for the purpose set forth.

6. The combination, with the horizontal reciprocating bar connected at one end with a rod carrying the hoe and provided with the centrally-located slotted arms, of a horizontal bevel-gear carrying upon its upper face a slotted arm, a pin adjustable in said slotted arm and engaging the arms of the reciprocating bar, and mechanism for rotating the bevel-gear, substantially as and for the purpose set forth.

7. The combination, with a cultivator, of a frame secured thereto, gear-wheels mounted in said frame, means, such as described, for operating the gear-wheels, a slotted arm secured to one of said gears, a pin adjustably secured in said slot, a bar having slotted arms in which the pin works, a rod secured to said bar and carrying a hoe, and a curved strip carrying a spool through which the rod passes, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES THOMAS JORDAN.
